Sheen requires 'new challenges'

Stan Rosenfield said his client's agreement with Warner Bros. is up this period, while CBS network has a contract for the hit show for at least 2 more seasons.

Charlie Sheen, who faces domestic violence, indicts stemming from a Christmas Day fight with wife Brooke Mueller, go into rehab in February. Rosenfield said his desire to leave the show is not connected to Sheen's anxieties about the pending court case. Rather, Rosenfield said, his client is looking on to other scopes.

"Charlie has completed this for 7 years. There is lot of new things to do, new challenges," he said. "He wants to do act lot of movies, & doesn't always get the opportunities during of the show."
